'Be itrknown that'I, Lou s HRPERLMAN, a citizen of thetUnited States, residing at New York, in the county-. 01 New York and State offNew -York-, haye invented certain new. and useful Improvements in Wheels; andl dohereby declare the following to be a full, clear, and exact description of the in-- vention, such as will enableothers skilled in; the art to w -ch itappertains to make and use the same. This invention-relates to mprovements in I demountable rims for cushioned tire Vehicle tionsandarrangements of parts as subsequentlyfspecified and claimed 7 7 In the. accompanying; ;draw1 ng,-

A bolt or boltdike device ;is extended:

through and fittedin each aperture 2 each formed with a preferably integral head 4: atone end, the shank being bored .longitudinally from the opposite head i to.

i019m a 1 3 recess 5'. jTherecess .5 is 1:

the shankiyin' each instance'is introduced through the respective apertures -.2,' andlat v the inside face-of'said web afnut 7 is pro vided andscrewed onthe threadedportiom structurefirmly in position engagement with the rim. (That portion fth sha kg I nearest the-head 4k is preferably "not thread. T

The partsbeing. ssembled. as described, i

and as seen in Fig; 1, the rim 1isapplied onto a wheel', such' as. seen at-B i'n'Fig. 1,

until the inneredge of the rim strikes; the

supporting stop fiange 9Iof the fixedrim or 1 felly bandlO of the wheel. Thereupon -the 1 tapered tip orjiwedge 'l'l of the bolt :12 is. projected into the recess'B; The partsare proportioned for causing the tapered tip or wedge 11 to. enter little off-center with respect to the recess 3, so'as to wedge'j'the;

rim over against the flange 9, and in the course. of; forc ngthe rnnover the innerenterintothethread grooves of theinutc? and thus'engage or bind the nut firmly so as to insure itagainst accidental displacement from the shank whilethe' parts are inoperatiye relation. 21' r ,Beferring to the .modilic'ation;as shown f I Figs. 6 and 7 of the drawing, it willgbev 105, j

this application further detail description seems unnecessary. These featuresare fully disclosed in my above referred to U: '8. Letters Patent in which the same are claimed.

7 An aperture (not shown) is provided in the rim 1 foradmitting the passageof the valve stem, and it is perfectly obvious that so. far as the present invention is concerned,

the rim may be" of the old style clencher 7 separation from the wheel.

This application is a continuation of and substitute for my concurrently pending application Serial No. 105,691, filed June 2%, 1916.

What is claimed is 1 l. The combination, with a wheel body and a demountable rim, of a shank extending-through the rim, means'for retaining the shank against disengagement with the. rim, the shank being formed with rim lock receiving means, and outwardly stressing and locking means-on the wheel body engaging the shank. Y

2. The combination, with a wheel body rim, of a headed shank extending through the webiof said rim, with a head on the exterior face of said web, means for retaining the shank against disengagement with the rim, the shank being formed'with rim lock receiving means, and outwardly stressing and locking means; on the wheel body engaging the shank.

3. The combination, with a wheel body and a demountable rim, or 'a headed shank extending through the web of the rim, with a head on the exterior face'of said web, means for retaining the shank against displacement with the rim, the shank being formed with rim lock receiving means, and
